goog.ui.MenuBarRenderer

Default implementation of canDecorate; returns true if the element is a DIV, false otherwise.

Creates and returns the container's root element. The default simply creates a DIV and applies the renderer's own CSS class name to it. To be overridden in subclasses.

Default implementation of decorate for goog.ui.Containers. Decorates the element with the container, and attempts to decorate its child elements. Returns the decorated element.

Takes a container and an element that may contain child elements, decorates the child elements, and adds the corresponding components to the container as child components. Any non-element child nodes (e.g. empty text nodes introduced by line breaks in the HTML source) are removed from the element.

Enables or disables the tab index of the element. Only elements with a valid tab index can receive focus.

Returns the ARIA role to be applied to the container. See http://wiki/Main/ARIA for more info.

Returns all CSS class names applicable to the given container, based on its state. The array of class names returned includes the renderer's own CSS class, followed by a CSS class indicating the container's orientation, followed by any state-specific CSS classes.

Returns the DOM element into which child components are to be rendered, or null if the container hasn't been rendered yet.

Returns the CSS class to be applied to the root element of containers rendered using this renderer.

Inspects the element, and creates an instance of goog.ui.Control or an appropriate subclass best suited to decorate it. Returns the control (or null if no suitable class was found). This default implementation uses the element's CSS class to find the appropriate control class to instantiate. May be overridden in subclasses.

Returns the default orientation of containers rendered or decorated by this renderer. This implementation returns HORIZONTAL.

Returns the element within the container's DOM that should receive keyboard focus (null if none). The default implementation returns the container's root element.

Initializes the container's DOM when the container enters the document. Called from goog.ui.Container#enterDocument.

Sets the container's state based on the given CSS class name, encountered during decoration. CSS class names that don't represent container states are ignored. Considered protected; subclasses should override this method to support more states and CSS class names.

Default CSS class to be applied to the root element of elements rendered by this renderer.
